SPECIFICATION forming part of Letters Patent No. 541,050, dated June 11, 1895.

' Application filed January 28,1895. semi No. 536,402. (No model.)

To all whom it may concern.-

Be it known that I, MARVIN MEAD, a citizen of the United States of America, residing at Monte Vista, in the county of Rio Grande and State of Colorado, have invented certain new and useful Improvements in Balingreference marked thereon, which form a part of this specification.

My invention relates to improvements in baling presses, and consists of the features; arrangements and combinations hereinafter described and claimed, all of which will be.

fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the s ri ngs,Figure 1 isa top or planview of my impre baling-press. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical longitudinal section taken through the balingchamber, showing the plunger-lever and the parts connected therewith in two positions and on a larger scale. Fig. at is a top or plan view of the power mechanism, the yoke being removed. Fig. 5 is a plan view of the powerbase. Fig. 6 is a section taken through the power-base on the line w as, Fig. 4. Fig. 7 is a cross-section taken through the baling-chamber to the right of the hopper (see Figs. 1 and 2) looking toward the left from lines y y, the parts being shown on a larger scale.

Similar reference-characters indicate corresponding parts'or elements in the views.

Let the numeral designate two bed timbers to which is attached the anchor-shaped base 6 forming the direct support for the circular plate 7 which is connected with the base by posts 8. An arm 9 is pivoted on a center pin 10 passing through the plate 7 and the anchor-base 6. This center pin passes through the inner extremity of the arm. The outer extremity of this arm is provided with an antifrictional roller 12.

Above the plate 7, and supported thereby, is the power yoke 13 comprising a casting carrying two dependinglugs 13. This yoke is journaled on a vertical pin or shaft 14 located to one side of the pinupon which the arm 9 is pivoted. The lugs 13 of the yoke are located on opposite sides of the pin 14. and are equi-distant therefrom. The roller on the arm 9 lies in the path of these lugs during a portion of each revolution of the yoke. Hence, the roller is alternately engaged by the two lugs 13" whereby the arm 9 is actuated twice during each rotation of the yoke.

To the pin on which the roller 12 is mounted is attached one extremity of the connecting rod 15, the opposite extremity of said rod being attached to a lever 16 fulcrumed on the framework 17 of the baling chamber 18. The baling chamber occupies a position intermediate the power mechanism and the lever.

As shown in the drawings, the lever 16 is angular in shape, and may be termed an elbow-lever. This construction allows the connecting rod attached to the lower arm of the lever to move in a line very nearly straight during the operation-of the plunger, and is therefore important. The lever 16 is connected with the plunger 20 by a pitman'19' the end of the hopper opposite the hinge 21.

Above the projection 21 and normally resting upon the framework 17 is a flange or horizontal projection 21 This flange is engaged by a spring 22 which allows the hopper a limited movement on the hinge 21 as the plunger passes under the projection 21. The spring 22, as shown, is bow-shaped, and its extremities are hooked under horizontal projections on the framework 17, the center of the spring being depressed to engage the flange of the hopper.

It is evident that the spring shown may be otherwise attached; also that any other suitable construction of spring may be employed.

Made fast to the bed timbers 5 and located adjacent the power mechanism is a plate 23 having one edge curved as shown at 23 to engage the roller 12 of the arm 9. The function of this plate is to check gradually the re- ICO bound or backward movement of the plunger, thus relieving the mechanism from the force of the shock or concussion incident to the unresisted return movement of a rebound plunger. This plate may be made of metal, or it may be constructed of wood having its curved friction face protected by a metallic strap.

Fulcrumed on the plate 23 is alever2t one arm of which projects into the path of the lugs on the power yoke. To the opposite extremity of the lever is attached a chain 25 or other suitable instrumentality adapted to pass around a sheave 26 located on one of the bed timbers 5. The opposite extremity of this chain is attached to a rod 27 which passes underneath the baling chamber and is connected at its opposite extremity with another chain or cable 28 which passes around a sheave 29 located on the framework 17. The opposite extremity of this last named chain is connected with a rod 30 attached to the plunger. Through the agency of the lever 24 and the means for connecting itwith the plunger, the return movement of the latter may be effected independently of the rebound incident to the expanson of the charge in the baling chamber.

The machine is operated by means of a sweep 32 having one extremity attached to the power yoke and further secured by a tie rod 33. To operate the mechanism, the yoke is turned in the direction indicated by the arrow. (See Fig. 1.) The lugs 13 on the yoke engage the roller 12 of the arm 9 and carry the arm along until the arcs described by the engaging parts diverge sufficiently to release the arm. During the movement of the arm in the direction of the yokes rotation, the plunger is driven toward the power mechanism through theinstrumentality of the connecting rod 15, thelever 16 and the pitman 19. The movement of the arm 9 is suiiicient to give the plunger the desired length of stroke. The material fed into the hopper is thus acted upon by the plunger and forced beneath the depending projection 21 of the hopper. This projection yields upward when engaged by a charge of material, but as soon as the plunger moves sufficiently in the reverse direction, the projection 21 moves downward behind the charge and folds the loose material so that it will be caught by the next charge, thus making a neat, compact bale. As soon as the arm 9 is released from the power yoke, the expansion of the charge in contact with the plunger causes the latter to rebound suddenly. As the arm 9 moves backward under the influence of this rebound, its roller engages the friction face 23 and gradually checks the plungers rebound as hereinbefore set forth. The movement of the plunger will be reversed after each forward stroke through the instrumentality of the lever 24: and its connections comprising the parts 25, 26, 27, 28, 29 and 30, the arrangement of the parts being such that the lugs of the power yoke engage one arm of the lever 24 and actuate it sufficiently to ad complish this result, just prior to the engagement of the yoke with the arm 9. Hence, the movement of the plunger may be reversed after each forward stroke, regardless of the rebound imparted by the expansive powerof a charge in the baling chamber.

Since the power applied to the connecting rod 15 during the operation of baling is a direct pull, said rod maybe made small as compared With a construction where the power is exerted by a push on the connecting rod. A smallconnecting rod in a m achineof this class is an important feature, since it reduces to a minimum the concussion orjar incident to the rebound, and also makes the work of the team easier sinceit diminishes the obstruction placed across the path or circle of travel.

Having thus described my invention, what I claim is-- 1. In a baling press, the combination with suitable power mechanism, of an upright elbow-lever having its upper arm fulcrumed on the frame and adapted to oscillate in a vertical plane, the baling chamber and plunger located intermediate the power mechanism and the lever, the pitman attached to the elbow of the lever at one extremity and to the plunger at the opposite extremity, and a connecting rod leading from the power mechanism and attached to the lower arm of the lever, substantially as described.

2. The combination with the baling chamber and the plunger, of the hopper hinged to the framework and having a depending projection extending into the baling chamber and terminating above the path of the plunger, and a spring engaging the folder-end of the hopper, substantially as described.

3. In a baling press, the combination with the baling chamber and plunger, of the hopper hinged at one end to the framework of the machine, the opposite end of the hopper having a depending projection forming a folder, and a flange located above the folder, and a spring engaging the flange, substantially as described.

4. In a baliug press, the combination with the plunger and baling chamber, of a rotatable yoke, an oscillating arm pivoted on one side of the yokes center and having an antifrictional roller lying in the path of projections on the yoke, a suitable connection between the arm and the plunger, and a tionary plate having a curved friction face adapted to engage the roller on the arm, a lever 24 fulcrumed on the stationary plate, and a suitable connection between one extremity of the lever and the plunger, the other extremity of the lever lying in the path of the rotatable yoke, substantially as described.

5. The combination with the baling chamber and plunger, and means for giving the latter the forward movement, of the stationary plate 23, and means for imparting to the plunger the return movement, comprising a lever 24.- fulcrumed on the stationary plate, a

suitable connection leading from one extremity of the lever to the plunger, suitable guide pulleys which said connection engages, and suitable means engaging the extremity of the lever for actuating the latter, substantially as described.

6. The combination with the baling chamber and plunger, of the rotatable yoke, means connected with the plunger, and actuated by the yoke, for imparting to the plunger the forward movement, a stationary plate 23, and means for imparting to the plunger the reverse movement after each forward stroke, said means comprising a lever 24 fulcrumed on the plate 23, a connection leading from one extremity of the lever to the plunger, and suitable pulleys which said connection engages, the opposite extremity of the lever'lying in the path of the rotatable yoke, substantially as described.

7. In a baling press, the combination withthe baling chamber and plunger, of the rotatable yoke, the oscillating arm actuated by the yoke, suitable connections between said arm and the plunger whereby the movement of the arm, when actuated by the yoke, gives the plunger the forward movement, a stationary plate 23 having a curved friction face lying in the path of the oscillating arm when making its return movement, and suitable means for imparting to the plunger the reverse movement after each forward stroke comprising a lever 24 fulcrumed on the plate 23, a connection leading from one extremity of the lever to the plunger, and suitable guides which said connection engages, the other extremity of the lever lying in the path of the rotatable yoke, substantially as described.

In testimony whereof I aflix my signature in the presence of two witnesses.
